It has been some time I used Ignition, so bare with me for ‘basic question’.
I am try to connect Ignition to Carlo Gavazzi Energy Meter via OPC-UA (Modbus TCP).
I manage to setup the device and get “Connected” in current status and also able to get the [Diagnosetic] information within OPC Browser.
My major problem reading the voltage, current and power details from the meter, the Modbus Manual is attached. The reading I need to have as SQLTag are between Modicom
address 300081 till 300219. (page.12 to page.13)
My problem is in the Addressing, I have read few time the Addressing section in manual and also tried few expriment, none give the correct reading, either the Connection get lost after I add to SQLTag, reading is abnormal or nothing happens.
Can someone please guide me on how to setup the addressing for this particular meter.
Thanks in advance
